What makes up the continents and the ocean floor?
The continental and oceanic plates are primarily igneous rock. The continental crust is granitic and the oceanic crust is basaltic.
Which rock makes continental and oceanic crust?
Continental crust is made of granite. Oceanic crust is made of basalt.
What are four differences between the oceanic crust and the continental crust?
1. The Oceanic crust is dense while the Continental crust is relatively lighter. 2. The Oceanic crust consists of Silicon and Magnessium, while the Continental crust has Silicon and Alluminium. 3. The Oceanic crust is thin, while the Continental crust is thick. 4. The Oceanic crust makes up the ocean floor, while the Continental crust carries the continents.
What is a characteristic of subduction?
The correct answers are - B. Where oceanic crust meets continental crust, and C. Earthquakes.Subduction zones appear only on places where a crust of lower density (oceanic crust) meets a crust of higher density (continental crust).On the places where the oceanic crust meets the continental crust, the oceanic crust goes beneath the continental crust, this makes changes and readjustments in the inner part of the crust, and plus there's significant pressure from the mantle layer from beneath, so earthquakes are a very common occurrence.Check all that apply. A. Broad river deltas B. Where oceanic crust meets continental crust C. Earthquakes D. Two continents collide
What do you call the crust making up the continents?
The crust that makes up the continents, or land masses on Earth is called continental crust. The crust that makes up the oceans is called oceanic crust.

What type of rock makes up the continental and oceanic crust?
basalt forms in oceanic crust granite forms in continental
What is the main type of rock in oceanic crust?
The crust is divided into two types: oceanic crust and continental crust. Oceanic crust, found under the ocean floor, is made of dense rocks such as basalt. It is about 7 kilometers (4 miles) thick. Continental crust, found under land masses, is made of less dense rocks such as granite.
What is the difference between continentalcrust and the oceanic?
Continental crust is thicker and less dense while oceanic crust is thinner and more dense, so essentially continental crust takes a higher position than oceanic crust. When oceanic and continental plates collide, oceanic plates slide underneath continental plates(if this makes what I said any clearer).
How is continental lithosphere different from oceanic lithosphere?
Continental plates are thicker and less dense. Continental plates are mainly granitic in composition. Oceanic plates are mainly basaltic in composition. The rock of continental plates is on average, much older than the rock of the oceanic plates. The oceanic plate underlies the oceans, and the continental plate makes up the land masses. Continental plates do not subduct at convergent plate boundaries.

Why does oceanic crust slide under continental crust during subduction?
The oceanic crust slides under the continental crust due to the differences in their densities. The continental crust is more felsic (contains more silica) which makes it lighter than the oceanic crust which is more mafic (containes more fe and mg). Because the process of subduction is very slow, gravitational forces have a stronger effect on the more dense oceanic crust, causing this crust to be pulled under the continental crust and down into the mantle.
What is two differences between the continental crust and oceanic crust?
The oceanic plate is thin, dense, and makes up the ocean floor. The continental plate is less-dense, thick, and make up the continents.
What do you call the crust making up the continents?
The crust that makes up the continents, or land masses on Earth is called continental crust. The crust that makes up the oceans is called oceanic crust.
What are the two types of crust that makes up the continents and ocean?
The two types of crust that make up the continents and ocean are the continental crust and the oceanic crust.
